RX 480 Vs. 380X?

hey guys,

well...my setup is finally complete, running stable and quick. My only gripe is if this graphics card (380X) is not cutting it. How will this compare against a RX 480?

I really need to get a GPU intensive game to see where we are. But today in counter strike I was dipping to frames low as 45-50 FPS :( OK, it was a busy server and I seem to get better results in a less crowded game?

does this sound right or is it time to upgrade??

hey dudes,

thanks for the quick response. i thought that too, its not the worlds most demanding game.

i havent had a chance to play a game to see where im at, what would be good to test? (DOOM)?

my specs are :
fx 8350
radeon 380x
128gb ssd
1tb data storage
gigabyte mobo (not sure on model)
16ddr3 RAM

im gaming at 1080p just now.

Great CPU!

What motherboard are you running? These CPU's are very susceptible to VRM throttling so cheap motherboards can have a big impact on performance, especially when running an overclock.
 
Motherboard is your problem, its a 4+1 VRM setup, how much case cooling have you got?

For these CPU's you really want a better VRM setup. BUT I spent a while experimenting with active cooling of VRMs and managed get a 8320 stable at 4.5.

Run IBT to max your temps, its not the CPU you are worried about but your motherboard. Monitor them at the same time as checking your CPU multiplier, you will see it drop.

First off the good news, you have heat sinks on them! Thats half the battle won already, now you just need to increase airflow directly to the heat sink. I suspended a 40mm fan approximately 10mm above the heatsinks and that lowered temps enough to prevent throttling.

how are you getting 40-50fps on CS, the 380x should be running that over 120fps, you are not sur it's a cpu issue, or anti virus scanning on background or something being installed ?
anyway the 480 is 30-40% faster than 380X

thanks for the input @Concrete .

i have real good airflow actually, i have a coolermaster and has two 120mm fans on the side panel, one 80mm on the backside behind CPU, one front and two on the top panel of the case.

can you dumb down what your suggesting please, i must admit im a noob :( at these things.

also to note : the lower the people in game, seems to boost my FPS more :eek:

yeah, i dont understand, but no soft / bloat were at all.

Might be best to keep an eye on the CPU clock speed while playing CS, that will give you a good idea if it's being throttled. It doesn't matter if you have a lot of fans around the case if the VRMs themselves aren't receiving enough cooling.

Another thing you could try is face the fans towards them and see if that does any better.

Another thing to check, what temps are you getting on both the CPU and GPU?

Useful final statement there. Now we know its your CPU choking the rest of your setup as CS:GO is CPU rather than GPU limited.

You need to install some temp monitoring software such as HWmonitor. Then a benchmarking tool, either Intel Burn Test (don't ask!) or Prime 95 will be fine for this.

Run the benchmark on a loop (or even better yet, run CS on a second monitor) and watch the temps, you will hit a certain temp and you will see your CPU frequency drop off dramatically for a number of seconds, then ramp up again.

This establishes a base line, then you experiment with airflow until you prevent the throttling.

EDIT: Wot he said ^.

the max i have gotten is 58c for the GPU and the CPU max is 37c?

does that seem right? it is after a short game at CS:GO, but both utilisied for GPU and CPU have hit 100%.

how do i get around throttling? do I need to OC?

Run something like Prime95 and open up CPU-Z, and see what speed it reports while Prime95 is running. 37c sounds too low, unless you have an amazing CPU cooler.

Overclocking will do the opposite, it will demand more power from the board. To get around the throttling issue you either underclock/undervolt the CPU to lower its power demands, or provide proper cooling to the VRMs (which is located at the headsinks next to the CPU socket). Hence me suggesting you pointing a fan to them.
